Should I limit the amount of time he listens to them just like TV, computer, or video games? It seems very different to me than the others. I went in ds's room to see what he was doing while listening, and at first he was playing with blocks (building a "plush house" like the one described in the book). The next time I went in, he was laying on his bed staring at the iPod speaker doing nothing else and lost in the "book." He can't get enough. He's listening to Half Magic by Edward Eager, a book first published in 1954!
